TO ALL PERSONS T0 WHOM'THESE PRESENTS MAY COME:

Be itknowu that I, LIYERUS HULL, of Charlestown, oi' the county of Middlesex, ofthe State of Massachusetats, have invented a new and useful Improvement in Whips; and do hereby declare the saine to be fully described in the following specification and represented in the accompanying drawings, of which- Figure 1 is an external view,

Figure 2 a longitudinal section, and

Figure 3 a transverse section of a whip made in accordance with my invention.

Figure 4 is a side view, and

Figure 5 is an end view of the stock, as prepared for being vulcanized.

. In making said whip, I employ cloth` covered with a vulcanizable composition, such as is known to and used by manufacturers of India-rubber goods. Such a composition usually Aconsists of caoutchouc or gutta perche. and

sulphur, or other matter, it being subjected a s uicient period of time to a temperature of about 300 Fahrenheit,

changed so as not to be taclre'j,r or`adhesive to an article when touched by it.

This cloth, with its vulcaniz'able composition in an adhesive orltackey state, I wind in a roll, and with a taper from oneend to the other, until I bring it Ato the necessary size for the stock or body of the whip.. Next, and preparatory to vulcanizing the composition of rubber or gutta percha on such cloth, I cover the roll with s. retainer or covering-ot' thread, which may be either wound or braided on the roll, the same being shown in figs. 4 and 5, in which a denotes theroll of cloth, and bthe retainer or thread covering braided ou the'roll.

Lhis retainer is necessary to hold the eloth in place during the heating-process of vulcanizing it.- Furthermore, the retainer compacts the roll, and adds to its strength, particularly when the said retainer is a braided one.

After having thus prepared the stock, and vulcanized it, it is'to be covered with one or more finishingooverings `c or with the same and one or more Turks heads, bands, or tubular or other devices, as fancy may dictate, the snapper or lash being subsequently added.

This'mode of'making a whip renders it very flexible and suitable for carters, mule-drivers, and others.

The external finishing-covering may bc of thread or leather, braided on the stock, or it may be of leather laid around and vsewed on the stock. i

I claim the whip-stock or body as composed not only of cloth, covered with a vulcaniz-able composition, and rolled up as set forth, but of a retainer or retuining-coverin,r of thread, either braided or wound thereon for the purpose of supporting the rali during the process of' vuleanizing itby heat.

I also claim a whip as composed ot the stock or body so made, and one or more coverings of thread, or leather,lor other suitable matcriaior materials, either wound, braided, or otherwise prperly iixed on such body'.
